Juice cleanses, juice bars, late night ads for juicing machines and the occasional celebrity endorsement all seem to be fueling a national juice-drinking craze. Fruit is healthy and fruit juice is a fast and convenient way to drink your nutrients, so what could possibly be wrong with a daily dose of orange, apple or cranberry juice or a trendy juice cleanse?

More than you ever imagined! While I am a fan of green vegetable juices, most juices contain too much fruit and therefore sugar. Here are 5 thoughts on how fruit juice seriously undermines your health – and why you should quit the stuff:

1. Think of your morning O.J. as soda — minus the bubbles.

OK, so you swapped your favorite sugary soda for cranberry juice, thinking that it’s better for you. Though I applaud the effort to ditch the soda, replacing it with a fruit juice sugar-bomb is a lateral move. Unfortunately, most fruit juices (organic or otherwise) flood your body with just as much sugar as soda pop.

For example, the average 12 ounce soda contains roughly 35 to 45 grams of sugar. The same amount of orange juice comes in at about 30 grams; apple juice delivers about 40 grams and pomegranate juice can top 45 grams. That's simply an insane amount of sugar to consume in one sitting, no matter what type of beverage it is.

What’s an acceptable amount of sugar intake? Ideally, no more than 10 grams a day at the most, which certainly takes fruit juice off the table!

2. There’s nothing to chew on.

Converting whole fruit into liquid requires a lot of processing. Along the way, the once-healthy fruit gets pasteurized, pulverized, filtered, pureed and stored in massive vats for months at a time, all of which chips away at the nutrients, vitamins and belly-filling fiber the fruit once had.

Then, they pump the liquefied fruit full of sugar. All that added extra sugar spikes your blood sugar because there’s no fiber to slow its release into the blood stream. Next, you get the crash, followed by hunger and cravings, none of which you’d experience had you eaten the whole fruit instead. And be aware of clever marketing claims.

No matter how they parse it, a glass of juice — with “pulp” or without, organic or otherwise — is not nutritionally equivalent to whole fruit, nor will it ever be. Remember, fruit juice consumption is not an acceptable short-cut on the road to good health. It’s more like the highway to health problems! So grab a real, whole, organic piece of fruit and start chewing!

3. How about a tall glass of heart disease and diabetes?

Another problem with a diet that’s heavy on fruit juice? Recent studies have indicated that it’s linked with increased insulin resistance and diabetes risk, whereas whole fruit consumption appears not to have the same health-eroding effect.

Fruit juices aren’t kind to your ticker either, according to one Harvard study. In it, researchers reported that daily doses of sugary drinks boosted heart disease risk in men. Fruit juices fall under the sugary drink umbrella, so my advice is to avoid all of them if you want to keep your heart, insulin levels, and waistline in check.

4. Hope you like going to the dentist!

If sugar highs and lows, increased insulin resistance, heart disease and diabetes risk weren’t enough of a disincentive, then at least consider your teeth. The acids in fruit juices, not to mention the mounds of sugar, can take a big bite out our your tooth enamel, resulting in weak spots that can blossom into costly cavities, which will eventually need fixing.

If the damage is significant enough, tooth bonding or crowns might also be needed to patch up the mess, so your wallet takes a hit as well. At that point you need to ask yourself if a fruit juice habit is really worth the damage, hassle and expense? Didn’t think so.

5. Did you know that 12 oranges died to make your orange juice?

In other words, it takes a heck of a lot of raw fruit materials and resources to produce a bottle of juice. Considering the resources used to fuel industrial farming operations – the pesticides, the millions of gallons of water for irrigation and the trucking all that fruit and juice — your morning beverage gives the earth a black-eye as well. Once again, you have to ask, is it worth it to batter your external and internal environments just for a fix of bottled sugar water?

How to kick the juice habit for good

For those of you with a serious juice jones, kicking the habit can be easier said than done, so here are a few pointers on how taper off and kick the juice bottle for good:

1. Buy green juices with as little fruit and sugar as possible. The less sugar the better.

2. Cut your dose. In a tall glass, add lots of ice, plus 3 to 4 parts water or seltzer to 1 part fruit juice.

3. Make your own. Blend your fruit and add water. Leave the peel on the fruit (unless it's a banana).

4. Toss in spices like cinnamon and nutmeg and a drop of stevia if needed.

5. Try a shot glass of portion control. In the morning, drink your O.J out of a 1-ounce shot glass, and stop at one shot.

6. Grow up – and switch to tea. It’s time. Tea is where it’s at. It’s tastes great and its body benefits are legion. Here are some tips on how to make the switch to tea.
